摘要

The dosing closure (6) has upper and lower circular closure disks (7, 8) that are rotatable and provided with openings for a passage of a bulk material (4). The closure is partially closed depending upon a turning position. The disks are adjustably arranged to each other at distance. The openings are formed as six congruent and radially running slots that are expanded to an edge of the respective disks. The lower disk has a conical filling material (22) arranged at a lower surface. A dosing chamber is formed between an emptying closure (5) and the dosing closure with defined dosing volume.
